A method for manufacturing a mechanical seal used in fluid applications, wherein the mechanical seal is comprised of a sintered (cemented) tungsten carbide ring that is turned on a lathe at a negative top rake angle instead of formed by grinding. The cemented tungsten carbide ring is initially prepared by rounding corners of the top surface to form a radii. The resulting mechanical seal yields significantly less surface damage, can be formed using faster cutting speeds and feeds than when grinding, enables formation of a greater range of complex geometries for the mechanical seals, and requires fewer passes than grinding. The compact is also formed at a significantly reduced cost as compared to grinding.
